Britain’s most notorious UFO case happened at a US airbase and it’s still a complete mystery

On 26 December 1980, two men claimed they saw a glowing object with coloured lights at Rendlesham Forest, just feet away from RAF Woodbridge - where the US Air Force was stationed.

The Ministry of Defence never investigated the events as a security matter, but there's enough physical evidence to label it an unexplained UFO sighting, according to Nick Pope, who used to work for the MoD.
